Suspect either a hose was left off during the previous work, or more likely it cracked after being removed and replaced. Start at intake manifold. look/touch all hoses and tubing coming off of it. Start with the biggest first

As long as the idle air control valve is working, ( I assume this is what you replaced, I would first check to make sure it is operating correctly), If it is, then Id begin searching for a vacuum leak

My car will have high revs or low revs at anytime and also just cuts out while I am driving.


Invest in a cheap OBD fault code reader from Amazon or eBay. This will help you pinpoint the problem(s)

2005 Opel Corsa lite switches off with irregular revs


Front right lower side is the crank sensor ,in line with the crankshaft ,could be this playing up although i have had many problems with this type of engine ,one problem is the computer bolted to the engine ,seem to suffer heat fatigue ,another problem i cannot explain is it just will not start and for this i fit a crank sensor from the earlier version with the toothed front pulley and support then cut the wires from the crank sensor and run them to the one at the front of the engine but they are polarised on the wires so if it doesnt start reverse the wires to the crank sensor ,Now no doubt iam wrong as ever but i do think that the crank becomes magnatised and its affecting the sensor so by moving it to the front pulley it eliminates this problem .

Rev out of control


Check to see if it has a Throttle positioning sensor. A faulty one will cause the engine not to run properly. It will do like you described with the engine revving and then wanting to cut out.

My opel Corsa lite Revs itself while idling or when I press the clutch while driving. The rpm stays @ 2.. What is the cause of this


A similar thing happend to me turns out it was the idle rev cold switch thing>
basically the switch which provides more fuel and revs when the car is cold, so that when you start the car it doesnt just die off.
the switch itself is a bit mechanical and is perhaps jammed on the full on position. If it happens more when the car heats up. then it is this switch.

what you can do is start your car one cold morning and see how high the revs are, if its still high then its probablly not the switch
